Facing challenges in developing or replacing transformers or reactors? Visit our booth!
Musashino Tsuko specializes in custom-made transformers and reactors, tailored to your specific requirements.
We offer solutions for:
• High-voltage power transformers for electron beam and X-ray systems, including insulation and corona discharge countermeasures
• High-frequency switching transformers for LLC resonant converters, focusing on leakage inductance, excitation tolerance, and efficiency
We also excel in reverse engineering, even for:
• Products with only hand-drawn schematics
• Products with unknown specs due to manufacturer closure
We redesign and reproduce such products to meet current standards.
Our in-house equipment supports development and quality:
• DC superposition testers for saturation characteristics
• Ferrite core grinders to control inductance tolerance
• Corona discharge prevention tools (e.g., vacuum chambers)
• Eco-friendly varnish impregnation systems
We provide one-stop service from design to mass production.
If you have any needs related to transformers or reactors, feel free to consult us.

Use Scenes (English)
• Harmonic current absorption and attenuation
→ Installed in the input stage of power circuits or inverters to suppress 3rd, 5th, and 7th order harmonics.
• Power factor correction and equipment protection
→ Improves compatibility with grid power, preventing malfunctions, errors, and unnecessary shutdowns.
• Noise suppression (EMI/RFI)
→ Reduces high-frequency noise and minimizes interference with surrounding equipment.
• Longer equipment life and stable operation
→ Minimizes heat and vibration, improving the overall reliability of reactors and systems. -
